Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, JOHN PARNELLE FIN- LEY, a citizen of the United States, residing at Vinton, in the parish of Caleasieu and State of Louisiana, have invented a new and useful J ournal-Bearing, of which the following is a specification.

This invention relates to journal-bearings, and has for its object to rovide a simplyconstructed and easily-app ied device of this character whereby the wearing parts may be readily renewed when worn or broken and the lubricating material replenished when required without disconnecting the parts or disarranging the machinery.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which the corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts may be resorted to without departing from the prin ciple of the invention or sacrificing any of its advantages.

In the drawings, Figure 1 is a perspective view from the lower side of the supporting member. Fig. 2 is a detached perspective view of the receptacle for the lubricant. Fig. 3 is a detached perspective View of the soft-metal half-box. Fig. 4 is a longitudinal sectional elevation. Fig. 5 is a transverse section of the same.

The improved device may be employed in connection with various forms and constructions of machinery, but is more particularly applicable to the journals of the bearingwheels of sawmill-carriages and for the purwhich a half-box 15 of relatively softer metal than the member 10 and formed with a lateral flange 16, bearing against the adjacent face of the member 10.

In the lower sides of the recess 14 channels 17 18 are formed, inwhich ribs 19 20 upon a receptacle 21 for the lubricant-bib to provide means for the slidable connection of the receptacle with the supporting member. The lower edges of the half-box thus bear upon the upper edges of the receptacle and prevent downward displacement of the box when the pressure of the shaft is removed for any cause.

The member 10 is provided with a perforated ear 22, extending laterally therefrom, and the receptacle 21 is likewise provided with a similar car 23, the ears for registering when the parts are united and receiving a cotter-pin 24 for retaining the receptacle in position.

The shaft for engaging the half-bearing 15 and for being lubricated from the receptacle 21 is represented at 25 and provided with the carrying-wheel 26, the latter bearing by its hub against the outer side of the flange 16. By this means it will be obvious that there can be no direct friction between the member 10 and the wheel 26, and all the end thrust of the shaft will be borne by the softmetal flange, and thus effectually prevent the contact of hard metal against hard metal.

By the simple construction herein shown when the half-box becomes worn or broken it is only necessary to elevate the structure supported upon the member 10-as, for instance a sawmillcarriage-by jack-screws or other power until the half-box is sufliciently clear of the wheel 26, slide the half-box out, and replace it with a new one and lower the structure into place again. This action requires the detachment of no bolts or other parts and can be accomplished in a very short time and with comparatively little labor.

When it is desired to replenish the lubricating material or to cleanse the cellar or receptacle 21, it is only necessary to remove the pin 24 and slide the receptacle out, refill it with lubricating material, and return it to place without delaying the machinery or interfering with other parts.

The improved device will be found espe cially applicable, as before stated, to the jourrial-boxes of sawmill-carriages which are subjected to heavy strains and exposed to dust and thus require frequent renewal.

and other foreign material and soon cut out,

Any device which will enable these repairs and renewals to be quickly and easily made is of great advantage, as will be obvious.

Having thus fully described the invention, what is claimed is 1. In a journal-bearing, a supportin member, having a longitudinal recess, a ha -bearing of relatively softer metal'than the supporting member and removably engaging said recess, and provided with a lateral flange bearing against the adjacent surface of the supporting member, whereby a relatively soft metal wearing-plate is provided for eXtending between the supporting member and the Wheel, carried by the shaft engaged by said halfbearing.
